How to create blank VOB equal to audio time? [Archive]

Is it possible to create a standard blank (video) .VOB that will expand and/or contract to be equal to the length of the subsequently multiplexed audiostream?

If not, how does one create a blank (video) .VOB of a specific duration, greater than the 99 seconds possible via "BlankVOB" by "jsoto"?

to be honest i am not aware of any program that will automate the length of blank video to suit the associated audio track, other than those programs designed to convert .mp3 songs to an authored dvd disc (run a google search, there are a few out there)

i usually import a blank bitmap (size to suit PAL or NTSC playback) into an authoring program (i use scenarist but muxman is an excellent free alternative) and set is a 'slideshow', then adjust display time to suit audio length.

The problem is, for my intended purpose, I'll have to create approximately 95 such .VOBs of varying durations.

Perhaps "jsoto" can provide me with a means of increasing the 99 seconds maximum of "BlankVOB" to an unlimited amount of time (It would be GREATLY appreciated!)...

The default duration for a still image in MuxMan is the duration of the segment's audio.

Hi!The default duration for a still image in MuxMan is the duration of the segment's audio.If MuxMan accepts a blank .VOB created by "BlankVOB" as input, this sounds like it may be just what I'm looking for ;>} Time to download!

EDIT - It was simple enough to use "MuxMan" itself to create a blank VOB of a 720x480 .BMP. I presently have "TMPGEnc DVD Author" generating a sample DVD for me - comprised of two blankscreen, audio-only titles.

UPDATE: For some reason, "TMPGEnc DVD Author", after accepting the multiplexed .VOBs (one of approximately 63 Mb and the other approximately 130Mb) for input has converted them to 18Kb audio-less .VOBs. Although this is overcome easily enough by substituting the .VOBs created by "MuxMan", I'd like to understand whether it's "MuxMan" or "TMPGEnc DVD Author" that's causing this anomalous situation...

@setarip_old

You can use a black BMP (blank VOB is not required) as video input for MuxMan.
If you add your audio, then MuxMan creates the "blankscreen, audio-only title".
You don't need to use TMPGEnc DVD Author afterwards.

If you get familiar with the mxp script, then even a menu can be made in the same pass.

Hi, and thanks for the feedback!You can use a black BMP (blank VOB is not required) as video input for MuxMan. If you add your audio, then MuxMan creates the "blankscreen, audio-only title".Yes, I had already discovered that when above I said, "It was simple enough to use "MuxMan" itself to create a blank VOB of a 720x480 .BMP." I had, at that time used "Muxman" to do exactly what you've mentioned ;>}You don't need to use TMPGEnc DVD Author afterwards.I was and am still hoping to use "TMPGEnc DVD Author" (as I have for many other past projects) to create a fairly formal menu.

More importantly, perhaps, I'm still trying to understand why the DVD structure created by "Muxman" is not processed properly by "TMPGEnc DVD Author".

Thanks again for your input!

@setarip_old

I have made a little test.

First I have made an "audio DVD" with MuxMan.
One title image and 12 mins audio WAV file.
After demuxing with PgcDemux I got:

AudioFile_A0.wav - 136.551 kB
VideoFile.m2v - 29 kB

Then I took MuxMans VOB files as input for TMPGEnc DVDAuthor.
After demuxing with PgcDemux I got:

AudioFile_A0.wav - 8 kB
VideoFile.m2v - 29 kB

Finally I took MuxMans VOB files as input for TSUNAMI DVDAuthor Pro.
After demuxing with PgcDemux I got:

AudioFile_A0.wav - 136.543 kB
VideoFile.m2v - 38.924 kB

Conclusion:
It works with TSUNAMI DVDAuthor, the successor of TMPGEnc DVDAuthor.
It seems the error was caused by the old version.

You can also see, that video in MuxMan is only one frame with the duration of the whole audio time.
Whereas the TSUNAMI DVDAuthor encodes the single picture to a complete video stream.
This way the room for audio on your DVD will be reduced.
In my opinion MuxMan is the better choice.

If you still want to use TMPG DVDAuthor, use it and , as last step, use VobBlanker to replace the PGC with the one created by MuxMan.

Perhaps "jsoto" can provide me with a means of increasing the 99 seconds maximum of "BlankVOB" to an unlimited amount of time This is just a thing to play with, but absolutely not-standard. One VOBU (a blank cell created by BlankVob is one VOBU) maximum length is 1.2 sec, according the standard

Hi!

Thanks for the tips ;>}

Still experimenting:

I have 95 48KHz .WAV files (named "1.WAV" through "95.WAV") and a blank (black) 720x480 .BMP file (named "Blank.BMP).

Question - Using only MUXMan v.0.15, is there a way to AUTOMATE the creation of one DVD containing 95 tracks?

@setarip_old

This is what I have done:

1. Written down the playtime of each track
2. Added the playtimes (without the last one) to get this list:

00:04:17:00
00:08:34:00
00:13:07:00
...
00:39:13:00

3. Converted the timecodes to framenumbers with PgcEdit's Celltimes plugin:

6425
12850
19675
...
58825

4. Import the list as chapters in MuxMan.

This works quite good in my test with only 10 tracks.
But I doubt it is precise enough for 95 tracks.
I guess it will go out of synchronization after adding some tracks more, because you don't know the absolut exact duration of a single track.
And its not so automated as I wish.

@goonixAnd its not so automated as I wish.Interesting approach, but it leads me to believe that the answer to my question is "No", there's no way using only MuxMan to automate the procedure I have in mind.

I'll probably just make 95 folders and use MuxMan 95 times to create 95 DVD "packages" - and then use some version of "TMPGEnc DVD Author" to add as 95 separate tracks/titles - Unless someone can enlighten me regarding a way to script what I'm trying to accomplish...

Be that as it may, your feedback is greatly and sincerely appreciated ;>}

While it's not automatic, there is no need to use anything other than MuxMan. To ensure sync make each song a segment, then make each segment a chapter. 0.17 would be better suited to this task if you want to use the GUI. It can also be done with a text editor in mxp, but that is also a lot of work. A wizard for this is on the to do list, but low priority (necessary features for 1.0, such as being able to create a menu using nothing but MuxMan's GUI, are at the top of the list).

To ensure sync make each song a segment, then make each segment a chapter.Actually, I'm making each song a separate track/Title. Since there's going to be nothing other than a blank (black) screen, I don't believe I have any synchronization concerns anyway - should I?While it's not automatic, there is no need to use anything other than MuxMan.Yes - and that's why I stated, "I'll probably just make 95 folders and use MuxMan 95 times to create 95 DVD "packages" - and then use some version of "TMPGEnc DVD Author" to add as 95 separate tracks/titles"...

What I finally wound up doing
1) Made 95 folders named "1" through "95", each initially only containing one of the 95 (48KHz) .WAVs, likewise named "1.WAV" through "95.WAV"

2) Used MuxMan 95 times to create one DVD "package" in each of the 95 folders (from a black blankscreen .BMP, coupled with the applicable .WAV file)

3) Used DVD2One's "Join" function, selecting "Seamless-Append to last titleset", in order to make each selection a CHAPTER rather than a TITLE, affording me the ability to readily select the tunes by number (So my world's not perfect yet - No menu with song titles)

I am now the proud possessor of a TRUE Video-DVD, high audio quality (NOT compressed) of my "Smithsonian Classic Jazz" collection ;>}

Again, my sincere thanks to all who have contributed information to this thread!

@setarip_old

Good you have managed to get your Jazz collection finally on DVD ;>}

Just for your information:

I'm followed the advice from mpucoder to load each track into a different segment
(using the GUI is only possible with MuxMan 0.16/0.17 - not free).

After a few mouseclicks I got a full working "audio DVD" where I can use the prev/next buttons like a standard audio CD.
No need to input the durations anymore, to use additional programs or to start MuxMan 95 times.

Can be worth to signup mpucoder's page.

To MPUcoder: there are plans for Muxman to be able to create dvd-audio discs?

mpucoder

23rd March 2006, 15:43

Not exactly. There are plans to add a wizard to make slideshows out of bitmaps and audio files. This is still DVD-Video, though.

23rd August 2006, 22:14

BTW there is a beta for a GUI to muxman which makes the creation of 95 audio files, each in its own chapter, with a video still to go with each, a very easy task.

See http://forum.gleitz.info/showthread.php?t=27415
(in German, don't know if there is an English-language thread)

What I finally wound up doingi'm trying to follow your guide with ac3 files and not with waves...

Used MuxMan..MuxMan can load ac3-5.1 files? (i used MuxMan i long time ago and don't remember)

Used DVD2One's "Join" function,,.have any other tool to do the same? (i don't have DVD2One)

thanks so much!
